DANGER
– Do not use high pressure cleaners
when there has been an oil spill; move
the appliance to another spot and avoid

+1200 µS/cm
er parts that can bring forth an increase
< 0,5 mg/l
in the engine speed.
– Risk of burns! Do not touch hot silenc-
< 20 mg/l ers, cylinders or radiator ribs.
– Do not put hands or feet close to mov-
< 300 mg/l
ing or rotating parts.
